California's Efforts to Clean Up Mobile Agricultural Equipment in the San Joaquin Valley (PDF- 203 KB)
The 2007 San Joaquin Valley 8-Hour Ozone State Implementation Plan
(SIP), approved by U.S. Environmental Protection Agency (U.S.
EPA), requires the Air Resources Board (ARB or Board) staff to present
to the Board in 2013 a regulation
for mobile agricultural equipment that moves California towards meeting
ambient air quality standards for the San Joaquin Valley by utilizing
the cleanest available technologies. Specifically, the
SIP includes a commitment to achieve emissions reductions of 5-10 tons
per day of oxides of nitrogen in the San Joaquin Valley by 2017
to accelerate progress toward attainment of the ozone
The attainment deadline is 2023.
In addition, a new SIP for the new 8-hour ozone standard for the San Joaquin Valley will be developed in 2014 for submittal to U.S. EPA in 2015. The SIP will address additional reductions needed to attain the new 2015 8-hour ozone standard by the 2032 deadline; likely through strategies that will rely on the availability of the cleanest technologies in mobile agricultural equipment. New SIPs will also be needed for other areas of the State. However, for these other areas, additional actions for mobile agricultural equipment beyond the emissions standards already adopted are not expected to be needed to meet the federal attainment deadlines.
ARB staff is proposing two rulemakings for mobile agricultural equipment. The first would implement the 2007 SIP and the second would be incorporated into the 2015 SIP. The near-term rulemaking, which would be submitted to the Board in late 2013, focuses on fully accounting for the voluntary actions by the agricultural industry to reduce emissions through their participation in incentive funding programs that accelerate the use of the cleanest available technology equipment (primarily Tier 3 and cleaner off-road engines in mobile agricultural equipment) in the San Joaquin Valley. Agricultural organizations working with the San Joaquin Valley Air Pollution Control District, ARB, United States Department of Agriculture Natural Resources Conservation Service (NRCS), and U.S. EPA, have signed a Statement of Principles that allows for a mechanism to be developed that will provide industry with credit for the investments already made to clean up mobile agricultural equipment. ARB’s action makes formal the written agreement already reached among the agencies.
Finally, in conjunction with the 2015 8-hour ozone SIP, staff will continue to work with the agricultural industry to develop a long-term strategy to increase the use of the cleanest technologies as they become available. This strategy would focus on the introduction of the cleanest technologies (primarily Tier 4 final engines) through incentive programs, regulation, or a combination of both to help meet the 75 ppb ozone standard by 2032.

In-Use Mobile Agricultural Equipment Regulation Survey
In 2009, the California State University, Fresno Foundation conducted a voluntary survey of agricultural operations throughout California in order to update the emissions inventory for off-road mobile agricultural equipment. The purpose of this survey was to collect data on population, operational characteristics, and activity of off-road mobile agricultural equipment in order to update the emission inventory. The survey also included questions about the types and amounts of commodities produced. This information is needed to ensure that a statistically significant sample is collected and to estimate a statewide population based on known agricultural production statistics.
